The clock periodically wakes up the user equipment. The dual mode time tracker uses a serving cell reference signal to correct timing errors of the user equipment clock with respect to a network clock while timing errors remain minimal and otherwise uses a serving cell synchronization signal to correct timing errors of the user equipment clock. The dual mode time tracker also sets a next wakeup time as a function at least of the size of the timing errors."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Correction of timing errors to enable long sleep times","description":"A mobile user equipment includes a user equipment clock and a dual mode time tracker.
